GATE.

Application filed J'anaury 24, 1921.

T 0 all whom it may concern.

Be it known that I, JOHN E. Posr, a citizen of the United States, residing at Durand, in the county of Shiawassee and State of Michigan, have invented certain new and useful Improvements in Gates, of which the following is a specification.

This invention relates to improvements in gates for closing relatively wide passageways.

The primary object of the invention is the provision of a gate for closing wide passageways, which is so securely mounted, and effectively braced, as to present small liability of sag or distortion in the gate, due to eccentric weight, or any weight bearing thereupon.

A further object of the invention is the provision of agate constructed with a view to -economical fabrication, in which the various parts canbe quickly and conveniently assembled to provide a durable, compact and rigid structure.

A further object of the invention is the provision of a gate having the above outlined. characteristics, which can be operatively mounted in a passageway, to swing centrally thereof or endwise of the passageway, depending upon the desire of the operator. v

()ther objects and advantages will be apparent during the course of the following detailed description.

In theaccom'panying drawings, forming apart of this specification, and in which like reference characters designate corresponding parts throughout the several views.

Figure 1 is a front elevation of the improved gate in closed position. 1

Figure 2 is a perspective view showing the improved gate in a partly open position. Figure 3 is a fragmentary cross sectional view of certain details of the gate construction;

Figure 4 is an elevation of details of the latch mechanism.

Figure 5 is a plan view of the latch mechanismshown in Figure 4.

Inthe drawings, wherein for the purpose of illustration is shown a preferred embodiment of 'my invention, the letters A and B designate posts or other supporting fence structures, which define a passageway. The gate C is pivotally mounted centrally thereof upon an axle bolt D to a. supporting Serial No. 439,550.

crane E, which supporting crane E is oscillatively mounted to the post B. A latch mechanism F is provided in conjunction with the gate to maintain the same in closed position within the passageway.

The posts A and B can of course, be of any preferred construction, and may be of wood, concrete or the like, the same merely designating the passageway in a fence enclosure.

The gate C is of special construction and preferably comprises a frame work 10, formed of a pair of substantially U-shaped tubular sections 11 and 12. The bight portions 13 and 14 of the sections 11 and 12 define the end of the gate frame. In order to connect the free ends or terminals of the arms 15 and 16 of the section 11, to the arms 17 and 18 of the section 12, connecting oints or sleeves 19 are provided. The sleeves 19 are integral in structure and are provided wlth the projections 20 and 21, having aligning bores therein. Thus in order to connect the sections 11 and 12, it is necessary to insert the free ends of the arms 15 and'16 into the projections 20 of the sleeves 19, and insert the free ends of the arms 17 and 18 of the section 12 into the bores of the projections 21. Since the sections 11 and 12 are the same size, it follows that such insertion of the various arms of the sections 11 and 12 may be readily effected. In their respective positions within the sleeve 19, the arms 15, l6, l7 and 18 may be welded, or otherwise suitably fixed; or they may be adjustably positioned therein, as desired. The sleeves 19 are provided with an extension 24-, projccting substantially at right angles to the projections 20 and 21, and provided with the bore or aperture 25 which projects through the extension 24:, and aligns with an aperture 26 upon the sleeve 19, directly 0pposite the projection 24-. It is preferred that the sections 11, 12, and sleeve 19 be of some approved material, such as galvanized iron or steel and covered with a foraminous wire structure 27.

The axle bolt D is preferably of a good grade of steel and provided adjacent each end with the screw threads 28, adapted to receive the spacing nuts 29. The axle bolt D is in reality part of the gate frame structure, since it aids materially in the bracing thereof and in assembling the same to the frame 10, the screw threaded ends 28 are inbis sorted through the apertures 24 and 26 of the sleeves 19. The axle D is of suflicient length that spindle bearing portions 30 and 31 project from the top of each of the sleeve projections 24. The extreme ends of the axle D are provided with the reduced screw threaded extensions 32, which are of course,

integral with the bearing portions 30 and 31. Suitable clamping nuts 33 are provided for adjustably positioning upon the screw threaded portions 32, and the application of these nuts will hereinafter be more specifically mentioned.

The supporting crane E is substantially U-shaped in formation and of tubular steel, comprising a bight portion 35, which is adapted to be pivotally mounted to the post B as by eye bolts 36 and 37 The eye bolts 36 and 37 are detachably aflixed transversely to the post B and maintained in position thereupon by the nuts 33. The supporting; crane E is much greater in height than the U-shaped sections 11 and 12 which comprise the gate frame, and in fact the extending arms 40 and 41 of the crane E are adapted to overlie the sections 11 and 12, and extend forwardly to have their forward ends 42 flattened and each provided with an aperture 43, to be pivotally mounted upon the bearing spindles 30 and 31 of the axle bolt D.

In assembling the gate C to the crane E, the axle D is as before mentioned assembled to the frame 10 and suitably positioned thereupon by means of the spacing nuts 29 in such manner that the spindle portions 30 and 31 project above the 24 of the sleeves 19. Since the main weight of the gate G will rest upon the arm 41 of the crane E. it is preferred to have the spindle 31 relatively longer than the spindle 30 in such manner that a bearing washer 45 can be inserted intermediate the flat end 42 of the arm 41, and the outer surface of the projection 24 as clearly shown in Figure 3 of the drawings. The arms 40 and 41 are assembled in such position that their apertures 43 are inserted over the spindles 30 and 31 and the binding nuts 33 are then clamped upon the screw threaded portion 32 of the axle bolt D, thus securely clamping the gate structure C for pivotal movement to the supporting craneE.

The latch mechanism F is of special construction, and preferably comprises a pair of arcuate latch arms 46 and 47 connected upon each side of the bight portions 13 and 14 to pivot, as by a pin 48. The pivoted latch arms 46 and 47 are provided with slots 49 or recesses, which are adapted to receive the projections 50 of a latch guard piece 51 which is riveted or otherwise secured for wardlyto each of the bight portions 13 and 14 of the sections 11 and 12. In this mannor the pivoting or oscillating action of each projecting portions of the arms 46 and 47 is limited. It is an additional feature of the arms 46 and 47 that their outer and free ends are provided with the cam surfaces 52. A retaining bar 53, may be suitably attached to the post A in order to cooperate with the arms 46 and 47 This bar 53 serves to cooperate in a manner similar to that which the bight portion 35 of the crane E serves in cooperating with the pair of arms 46 and 47 which are mounted upon the bight portion 14. Thus when the gate is closed, substantially as shown in Figure 1 of the drawings, the arms 46 and 47 upon each of the bight portions 13 and 14 are swung outwardly therefrom in their most forward position, until the free end of each arm 46 and 47 is disposed upon either side of the retaining arm 53, or the bight portion 35. WVhen in this position, the gate C cannot be moved from its closed position. However, when it is desired to. swing open the gate, one or both of the arms 46 and 47 are pivoted in their rearward position substantially as shown in Figure 5 of the draw,- ings for the arm 47, and when in thisposition the gate C can be swung to clear the passageway as defined by the posts A and B.

As before stated, the gate has been provided in order to balance the strains incident to eccentric weight, and this is readily effected, since the gate C is centrally pivoted to the supporting crane E substantially as above described. Thus the gate C is pivoted substantially at its center of gravity, and when the latch mechanism F is opened at each end of the gate structure C, the gate C will of course pivot upon the supporting crane E by means of the axle bolt D rotating with movement of the frame 10 and the spindle portions 30 and 31 bearing within the apertures 43. Inthis manner substantially one-half of the passageway can be used. However, if it is desired to use the entire passageway as defined by the posts A and B, the latch mechanism F adjacent the post B can be left in locked position with respect to the bight portion 35, while the latch mechanism F adjacent the post A can be opened and the gate can then be swung so that the supporting crane E pivots in the eye bolts 36 and 37 andthe entire passageway may be cleared. However, even if both of the latch mechanisms F are open, the gate C can be turned in its pivot in the supporting crane E to clear only one half of the passageway, due to the easy pivotal movement centrally of the gate, and with respect to the relatively difficult pivoting movement of the supporting crane E in the eye bolts 36 and 37.

In order that the gate C may be raised or lowered to suit particular conditions, such as snow upon the ground in winter, and the like, a series of apertures 55 are provided in the bight portion 35 of the crane E and adapted for receiving the pin 56, which in reality supports the crane E upon the eye bolt 37 Various changes in the shape, size and arrangement of parts may be made with the form of the invention herewith shown and described, without departing from the spirit of the invention or the scope of the claims.

I claim:

1. A gate, comprising in combination a pair of substantially U-shaped sections of bent bar material, sleeves connecting the free ends of said sections to form a rectangular structure, spindles projecting from said sleeve connections, and a substantially U- shaped crane support element pivoted at its free ends to said spindles, and extending over and from said first mentioned gate sections, as to permit complete rotation of said rectangular structure on its pivot and through said crane.

2. In a gate structure, thecombination of a gate frame comprising a 3 ir of substantially U-shaped sections, means for detachably securing said sections together at their free terminals, an axle bolt vertically positioned in said gate structure through the connecting sleeves thereof to provide upwardly and downwardly extending spindle bearing ends, and a supporting frame of tubular U-shaped construction having the free terminals thereof flattened and transversely apertured, the gate structure adapted for having the spindle bearings thereof inserted into the apertured ends of said U- shaped supporting frame, and whereby the gate structure may be rotated through 360 with respect to said supporting frame.

3. As an article of manufacture, a gate comprising a pair of substantially U-shaped sections, sleeves for supporting the free ends of said sections, and an axle bolt vertically and detachably mounted upon said gate and within said sleeves, said bolt having bearing spindles thereon.
